What to do when your sanity needs a sweat sesh, but making it to the studio is just not going to happen? Sweat Series is here to help! We partnered with Athleta and tapped the industry’s hottest instructors and fit-stagrammers to give us their quickest—and hardest—do-anywhere workouts. So, get pumped! (On your own schedule.)

For this five-minute, tough-as-a-ballerina workout, just grab your dining room chair and get to work.

Created by mom-and-daughter duo Lauren and Rachel Piskin, ChaiseFitness focuses on giving you toned arms and lean legs using dance-inspired strengthening exercises.

But just because the moves are graceful doesn’t mean they won’t give you results.

It’s not always the hardest and most complicated workout that’s going to change your body the most.

“It’s not always the hardest and most complicated workout that’s going to change your body the most,” mom Lauren, a former professional figure skater, explains. “Dancers are a prime example–they think about strengthening, lengthening, and perfecting their posture—but are some of the strongest athletes out there.”

And they should know: Rachel began training as a ballerina as a young girl—and eventually joined the New York City Ballet as a teen. After an injury sidelined her career, she found her way back to health through fitness. Eventually, the super-athletic mom-daughter duo opened ChaiseFitness, whose classes combine Pilates, ballet, and cardio at four locations in Manhattan (and one coming soon to Madison, NJ).

For a do-anywhere super-strengthening workout, do the Piskins’ five minute chair workout, above—and check out the rest of our butt-kicking Sweat Series workouts here.
